Edwards Active and Passive range of gauges and controllers

With gauges being vital to any vacuum system in order to efficiently control and monitor processes, you can find a wide selection of technologies to best suit your application. And it is now an even wider range with the addition of our new Passive range.

In all cases we offer gauges that span the complete range from Atmosphere to UHV pressures

Edwards active gauge range

Active gauges

Active gauges are a complete self-contained head and driver electronics in a compact unit. These gauges typically need 24 V dc and then provide a 0-10 V output that relates to the pressure. This output can be S-shaped or Linear depending on the chosen unit

Edwards digital gauges range

Digital gauges

Digital gauges are similar to Active in that they are self-contained including driving electronics, however they take this one step further and eliminate the need for a separate controller. The Digital gauges simply need a supply voltage in the range of 15 to 48Vdc and then are serial comms enabled, so can be directly interrogated via a PC or PLC using either RS232 or RS485 communications.

Edwards passive gauge range

Passive gauges

Passive gauges completely separate the measuring part from the driver electronics. The head that is attached to the system only contains the items needed for the physical measurement and all other electronics is contained in the controller. As such the controller and cable have to be specific to the desired gauge.

Edwards P3 portable handheld gauge

Portable gauging

Portable gauging offers the opportunity to be free of cabling and power and take spot measurement checks. The Edwards P3 handheld all in one measuring system is the essential device for on-site service calls and on the spot flexible checking due to it being mains power independent
